Before you can issue invoices through a licensed e-invoicing provider (YPAHES), you must declare your provider on myDATA, the e-invoicing platform of AADE (the Greek tax authority). In Wrapp the declaration takes just a few minutes, right inside the app. Here are the steps.

### Step 1: Log in to your account

Log in to your account at [wrapp.ai](https://wrapp.ai/).

### Step 2: Open Settings

From the top right of your screen, go to the **Settings** menu.

### Step 3: Go to the YPAHES Provider Declaration

In the inner settings menu, select `Integrations → YPAHES Provider Declaration`. Several fields will appear on the right side of the screen. The green ones are already pre-filled.

### Step 4: Fill in your TaxisNet credentials

Fill in the empty fields with your TaxisNet credentials (the login you use for Greek government tax services).

### Step 5: Click the myDATA declaration button

Click the **Declare on myDATA** button. If everything went well, the fields that were previously white will turn green, confirming that the process completed successfully.

**Important reminder:** Do not forget to forward the original contract you signed with your IT Solutions Provider to your accountant. By law, the contracting parties are required to file it with the competent tax office (DOY).
